PURPOSE:To suitably warm up a temperature of an electric blanket when waking up in the morning, by adding a clock function to a temperature controlling function, setting an alarm time, and changing a set temperature automatically when approaching said time. CONSTITUTION:A temperature of an electric blanket is set by a temperature setting circuit 26 by operating a temperature setting dial 9. Also, an alarm time is set by operating a slide switch 4 and registering keys 2, 3 of an operation key part 34. A microcomputer muCM31 stores a correction time of a value for subtracting a preset constant value from the alarm time, as well as the alarm time which has been set. When it is detected that the present time has coincided with a corrected time in the morning, a constant value beta is added to a set temperature which has controlled a temperature before that time, and a subsequent set temperature is newly set a little higher. In this way, a temperature of a blanket becomes somewhat high a little earlier than an alarm time, a temperature correction in the morning is executed when an alarm sounds at an alarm time, and it is possible to wake up in an agreeable temperature state. |
